A car allows me to get to a destination for specific purpose. For example, I don't "go to work" any more. I work where I am. Most of the time this is from my home. Other times, it requires that I be in proximity and cooperation with others. The car gets me to this work. Had not my employer contracted to use a specific location for this communal work, ie "the office", then all the participants would travel to a mutually agreed upon facility. In a car. With a self driving car I could continue to work where I am.

I do understand that my work allows for this. And that this is not true for everyone.

What interests me about my comment is that I now see that my advocating for mass public transport needs to be reviewed to account for the current facts and numbers regards who (workers in this case) that could actually take advantage of it.
